This case study highlights hypoprothrombinemia-lupus anticoagulant syndrome, a rare bleeding disorder. Early diagnosis through specific coagulation tests is crucial for effective treatment and improved patient outcomes.
Area of Science:
- Hematology
- Pediatric Medicine
- Clinical Immunology
Background:
- Recurrent epistaxis in children can indicate underlying coagulation disorders.
- Prolonged activated partial thromboplastin time (APTT) necessitates further investigation into specific clotting factor deficiencies and inhibitors.
Observation:
- A young boy presented with recurrent epistaxis and significantly prolonged APTT.
- Laboratory tests revealed the prolonged APTT was uncorrected, with positive lupus anticoagulant and low prothrombin activity.
Findings:
- The patient was diagnosed with hypoprothrombinemia-lupus anticoagulant syndrome.
- Treatment with glucocorticoid, immunoglobulin, and vitamin K1 led to clinical improvement, normalized prothrombin activity, and persistent positive lupus anticoagulant.
- Six-month follow-up showed no recurrence of epistaxis.
Implications:
- This rare syndrome requires specific diagnostic tests, including APTT correction and lupus anticoagulant assays.
- Early detection and prompt, targeted treatment can significantly improve prognosis in patients with bleeding symptoms and coagulation abnormalities.

Epistaxis
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Disorders of Hemostasis
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
